MANUFACTURE OF OIL- PRESS MATS.

SPECIFICATION forming part of Letters Patent No. 280,460. dated July 8, 1883,

Application filed February 3, lfit'ih To all whom, it may concern Be it known that we, OYRUs ESKRETT and WILLIAM HENRY SEARLE, subjects of Her Britannic Majesty Queen Victoria,-and, resi- 5 dents of Hull, in the county of York, England, have invented a new and useful Improved Manufacture of Wrappers or Envelopes Used for Extracting Oil from Seeds and in Oil-Cake Making, of which the following is a specifica- IO tion.

Figure'l is a side View of a wrapper made according to our invention. Fig. 2 is an illner face View of the same.

This inventi 011 consists of an improved manu- I 5 facture of wrappers or envelopes used in the oil-presses for extracting oil from seeds, and in the making of oilcake, which wrappers or envelopes have hitherto been made of horsehair, wood, paper, or metal.

In the manufacture of wrappers or envelopes according to this our invention, we employ for the two halves of the wrapper or envelope A a material known as vulcanized fiber. The material aforesaid is cut to the required 2 5 shape and size. The usual cross-grooves, B,

(No mode-l.)

are cut or scooped out of the inner surface of each half of the wrapper or envelope A by suitable cutting-tool, and the two halves are hinged or jointed together by leather in the usual manner, as shown at C.

The Vulcanized fiber is a material admirably adapted for the purpose herein set forth, as wrappers constructed thereof possess the following advantages: lightness, moistureproof, may be subjected to great pressure without injury, and are very durable.

We are aware that prior to our invention wrappers or envelopes of the form and construction shown by the drawings were used, and to such we lay no claim; but

sire to secure by Letters Patent, is-

The improved manufacture of wrappers or envelopes made of vulcanized fiber, for purpose herein described.
